A572 High Strength Steel Angle Iron
A572 angle steel, also known as angle iron, angle steel, L-shaped bracket, section steel or angle steel, is a hot-rolled HSLA product. Malleability is one of the key characteristics of angle steel iron, as they are often used in reinforcements and building fixtures to strengthen corners, as well as for general reinforcement of objects such as bridges and arches. All angles have an L-shaped cross-section, and although 90° angles are most common, they can be designed with equal or unequal leg lengths according to customer specifications.
